Starting the Runtime in Cluster Mode in Studio
| Mule Runtime Engine versions 3.5, 3.6, and 3.7 reached End of Life on or before January 25, 2020. For more information, contact your Customer Success Manager to determine how you can migrate to the latest Mule version. |
A new feature in Anypoint Studio July 2014 allows you to specify that the Mule runtime should start in cluster mode for specific applications. Running an application with this setting enabled will cause it to run as if it were on a one-node cluster. This allows you to test for any discrepancies in the application’s behavior between the clustered and the standalone modes.
You enable cluster mode via the run configurations for your application.
To access the run configurations for your application, select Run, then Run Configurations. In the left-hand pane, select your desired application or click the 
icon to create a new run configuration.
In the run configuration’s General tab, click Start as cluster node. You can enter a cluster node ID or leave this field blank to let Studio assign a random ID.
